My health has hit it's first major declines in the last 6 months where I'm spending more time in hospitals and the ER and have spent about 6 months on oxygen day and night. I started some rehabilitation therapy to help pull me off oxygen so I don't continue a downhill fall and can start compensating without 02. I am doing amazingly well during the day and continue oxygen at night. I have done better at work where I'm active my entire shift and in general daily activities. I used to be involved in tons of athletics like cross country, track, and soccer. I just sat out a while to deal with beig sick when it happened. The most difficult thing for me being really sick is feeling so trapped and not being able to escape and be active. Running and biking is what I really love and I feel so restricted not being able to go out. So my question is am I totally jumping the gun attempting to exercise? Maybe starting with a jog/walk depending on how I do during it. Could it be good for my lungs, and managing infections to try to exercse again? Or with the situation does it sound risky and detrimental to my health? I just want to run!!!! And my favorite 5k is in 2 months and I want to go even if I can't run it all! So I need advice. I would greatly appreciate any input or suggestions on regaining my health and abilities! Thanks!
